How do Sargent's ideas apply to today's inflation challenges?
My work on the 'conquest of inflation' is directly relevant. It emphasizes the critical role of expectations. If people expect inflation to remain high, they will act in ways that perpetuate it. Conversely, a credible commitment to price stability by the central bank can anchor inflation expectations downwards, making it more effective in combating persistent inflation. The credibility of the policy maker is paramount.
